Madoff fraud puts focus on fund due diligence

As a swath of investors reported sizable exposures to New York-based broker and hedge fund manager Bernard Madoff, several market players that conducted due diligence on his firm told Risk it raised danger signals as far back as the late 1990s.

Madoff was arrested on December 11 and charged with securities fraud for an alleged multi-billion dollar Ponzi scheme, in which principal payments from new investors in Bernard Madoff Investment Securities (BMIS) were used to finance redemptions elsewhere. Days earlier, at his Manhattan apartment, Madoff allegedly confessed to his own sons - both senior employees at the firm - that the fund was "just one big lie" and that he was "finished", according to a Securities and Exchange Commission (SEC) complaint.

As of January 2008, the firm had $17.1 billion in assets under management and served 11-25 clients, SEC filings show. "All I can say is this is a real tragedy and we are doing everything we can to minimise the losses," says Madoff attorney Ira Sorkin, of New York-based law firm Dickstein Shapiro.

On December 16, SEC chairman Christopher Cox said the supervisor would conduct a review of its reaction to "credible and specific allegations" concerning Madoff, which dated back to at least 1999.

Many large and otherwise sophisticated dealers and funds of funds have been hit by the alleged fraud. Among them, BNP Paribas reported an exposure of EUR350 million ($492 million) to the fund stemming from its trading business and collateralised lending to funds of funds, while HSBC admitted it may have lost approximately $1 billion from providing financing to institutional clients that invested in Madoff. Man Group similarly reported a $360 million exposure to funds advised or sub-advised by BMIS, via its Switzerland-based fund of funds. According to the SEC indictment, Madoff himself believed total losses from the scheme added up to an eye-watering $50 billion.

Although the scale of the alleged scam has shocked onlookers, some market participants are not surprised by the accusations of manager fraud. In fact, investors who didn't put money into the fund say there were a number of red flags that should have warded off potential clients. One was a lack of sufficient independent oversight at BMIS, which didn't have a relationship with a major auditor.

"He was doing custody, trading and administration. That was a big red flag," says one London-based fund derivatives dealer at a large European bank. According to those who had conducted due diligence on BMIS, the multi-billion-dollar operation was audited by a firm operating on the outskirts of New York with three employees - one of whom was 78 and living in Florida.

Sources say Madoff was difficult to meet in person and often cancelled appointments due to illness. "He was very forthcoming in his excuses," recalls one US-based hedge fund manager who tried to meet with him. Madoff was also unable to answer basic questions about BMIS, such as how it was organised, what kind of clients it catered for and how much money it managed, he adds.

The popularity of BMIS meant some banks were approached on an almost monthly basis with requests for leveraged trades on the fund. Due to the highly risky nature of such business, which requires the dealer to carry underlying fund shares as a hedge, banks often insist on the use of managed account platforms. But Madoff is said to have refused approaches to set up managed accounts, even when the rejection jeopardised potential investments of as much as $1 billion.

However, the most curious aspect of BMIS was its investment performance. Madoff claimed to be conducting a split-strike conversion strategy, also known as collaring. This involves selling a protective put option while simultaneously buying a covered call option. This strategy should outperform a long stock position while capping upside and downside, analysts say. Nonetheless, market participants who analysed position reports and other information about BMIS remained mystified at how the fund earned such high and stable returns. "I tried to replicate his strategy," says the London-based fund derivatives dealer. "There's no way the strategy he was describing to me was making the money. So it was something else: a black box."

Bewilderment at Madoff's track record spawned accusations the firm was front-running client orders or was engaged in some kind of regulatory arbitrage involving its brokerage unit. The SEC found three violations of best-execution rules during an examination of the firm in 2005, according to an agency spokesman. Best execution rules stipulate brokers must execute orders at the most favourable available terms for their clients, taking into account speed, pricing and likelihood of execution.

With so many question marks hanging over BMIS, why did it continue to attract investment? "Most people have a list of acceptable third-party administrators, prime brokers and audit firms, and this guy would have failed on at least two of those, so people would have to effectively overrule their standard policies," says one London-based hedge fund derivatives dealer at a large US bank. Madoff's long career history may have helped, which included a spell as a member of the board of governors of the National Association of Securities Dealers and chairman of the board of directors at Nasdaq. Madoff had also served on various SEC industry panels.

But the most alluring factor was simple, suggests the US-based hedge fund manager: "If you looked at his track record, it was one of the most phenomenal track records you could ever behold. People were intoxicated by returns."
